Why won’t my free proxy node connect? This guide helps you distinguish between an inactive node, traffic not being routed through the client, a restricted exit IP, DNS issues, and conflicting browser settings. It applies to common clients such as Clash, V2Ray, and sing-box. Check each item in order, changing only one setting at a time to avoid making things more complicated.
1. First, check whether the node is down or the proxy isn’t working
Turn off the proxy and visit a website that normally works without it. If that site still won’t load, check your Wi-Fi, mobile network, or router first. Once your basic connection is working, open the client and check the following:
- Update your subscription and check the result. If the update fails, the list may still be showing an old cached version. A successful import also doesn’t guarantee that a node is working.
- Make sure you’ve selected a specific node, or that the proxy group points to a working node—not “Direct,” “Reject,” or an unavailable option.
- Enable the appropriate traffic-routing mode. Desktop clients typically use the system proxy, while mobile clients usually require permission to establish a VPN connection. Grant permission as prompted by the client.
- Temporarily switch to global proxy mode and visit the target website. If it loads, check your routing rules first. You can switch back to rule-based mode after testing.
- Try another node, then test over both Wi-Fi and mobile data to see whether the issue changes with the node or network.
A latency test returning a value doesn’t mean a webpage will load. It may only check whether a specific test address is reachable. Free nodes can stop working due to maintenance, congestion, or access restrictions, so the results of an actual browsing test are more useful.
2. Understand IP issues: a connection failure is different from a website denial
If the client keeps timing out and you can’t access multiple websites, the node may be unreachable or your current network may be restricting access. Try another node or network, and check that your device’s clock is set to sync automatically. A significantly incorrect time can cause certificate verification to fail.
If most websites work but one shows a CAPTCHA, a 403 error, or a location restriction, that doesn’t necessarily mean the node is down. A shared exit IP may trigger the target website’s security checks. A single website denying access doesn’t mean the proxy connection has failed. Try a node with a different exit IP to verify, and avoid repeatedly logging in or refreshing the page.
3. How to check DNS without making things more complicated
Focus on DNS if domain names fail to resolve, the browser says it can’t find the server, or the logs show DNS errors. First, restore the DNS settings recommended by the client. Check whether other VPNs, accelerators, or DNS tools are running, and temporarily disable any conflicting software before trying again.
Your browser’s “Secure DNS” setting may use a different resolution path. Note the original setting, then temporarily turn it off and compare the results. If you’ve manually changed your system DNS, you can also restore automatic settings first. Don’t change DNS in the system, browser, and client all at once. Restart the browser after making changes, and clear the system DNS cache if needed. Opening a website by its IP address can be affected by HTTPS certificates and other factors, so it shouldn’t be your only test.
4. If only your browser won’t load pages, check its settings
If other apps work normally, try opening the same page in a private window or another browser. Private browsing doesn’t guarantee that all extensions and proxy settings are bypassed, but it can help identify interference from cached data, cookies, or extensions.
Check whether a proxy extension is overriding the system proxy, temporarily disable unnecessary extensions, and clear data only for the affected website. If the site works in another browser, focus on the browser’s settings; there’s no need to reinstall the client right away.
If the problem persists, note the client version, error message, network type, and troubleshooting steps you’ve tried, then test with a recently updated free node. Before asking others for help, be sure to hide your subscription link, node password, and token to avoid exposing your configuration.
